The visual differences between a Mazdaspeed 6 and a Mazda 6 sedan are minimal. While the normal 4 cylinder Mazda 6 has a 2. Let me explain what this means. Well, it does, but by the same way a 2JZ means something. It stands for Direct Injection Spark Ignition. Remember when I said the normal Mazda 6 had port injection?
Direct injection is where the injectors are in the cylinder, so the fuel and air gets mixed after the valve. Why is this important you may ask? Well, with some weird sciencey magic, direct injection is more direct throttle control. Which is bad. This includes the already weak connection rods, the horrible HPFP high pressure fuel pump , among other things. The turbo is great, the engine is pretty good, and I have no complaints in that department.
Let me explain. Mazda stopped producing this engine in The 2. It is made of aluminum alloy, has cast-iron sleeves and a cassette type balancer unit. The turbo version was equipped with a forged steel crankshaft with eight counterweights, sinter-forged connecting rods, and pistons with the new shape adapted for the direct injection.
There are oil jets in the block for lubricating and cooling the pistons. The L3-VDT has an aluminum cylinder head, the chain-driven double overhead camshafts, four valves per cylinder. The engine was equipped with a more durable roller chain instead of a pinned link timing chain in the naturally aspirated version.
The intake camshaft also drives the high-pressure pump for the direct injection system. There are two intake valves and two exhaust valves per cylinder which have valve angle of 39 degrees.
Solid tappets actuate the valves. Intake valve lift is 9. Also, among the various fuels on the market, we are studying the use of flex-fuel. View More.

The cylinder block and cylinder head are made using a new implementation of the Advanced Precision Mazda Casting process, which increases their strength. In addition, cross drilling between the block liners and between the valve bridges on the cylinder head improves resistance to heat.
The crankshaft and connecting rods are made of steel, the diameters of the connecting pins increased, the shape of the rods optimised, full floating pistons introduced, and made to ensure that all moving parts are stronger, more rigid and more durable.
Special effort was made in the tuning of the exhaust to optimise torque output and present an appealing exhaust tone that heightens the Zoom-Zoom driving experience. The shape and size of the inner diameter of the exhaust pipes and the internal structure of the silencer produces a throaty, sporty sound when accelerating from a standing start from a low speed, and a pleasing linear curve at high speeds. The exhaust system also adopts a tailpipe with attached diffuser that enhances the sporty appearance.
